Shared Hosting

A shared web hosting service refers to a service where your site is held securly on one of our many large, high availability servers with many other customers to share the costs. Ideal for small websites that don't need very unique requirements or large amounts of space or bandwidth.

Email Hosting

Implementing an email server in-house requires capital hardware expenditures and regular costly maintenance. Hosting your email off-site with a service provider that specializes in email management provides many benefits.

Dedicated Server

A dedicated server lets you lease an entire server not shared with anyone, giving you greater flexibility with the business applications you run, operating system you prefer and more.

Back-up Servers

Has your data outgrown your server? Does your business-critical data need serious fault tolerance.

My website is not sending email and my web forms do not work and I am getting 550 authentication errors

Problem

Your website is not sending emails properly from your contact page, web forms or web applications or you are getting bounced emails from your website.

Proper website and email hosting server compliance requires that your servers can not be used maliciously to send emails or spam and require proper authenticated users access only. This measure helps reduce spam and fishing scams on the Internet. For example, if your website is currently set to use phpmail() functions or sendmail functions (without "qualifiers") then any emails sent to addresses not on your domain will fail and not leave the server.

If you are a site or mail admin you may see postmaster emails with a similar error message:

550-You do not have sufficient privileges to send mail to this address.
550-Please authenticate and try again.

Solution

To resolve this problem, the ideal solution is to use an SMTP authentication method from your website. This method will pass your username and password to your mail server along with the email to validate you are a permitted user to use this servers resources and send emails to the world.
